Description

DETAILED DESCRIPTION OF THE INVENTION Technical Field The present invention relates to an information storage device, in particular, a method for sequentially reading out image information recorded on a plurality of recording media in the form of electrical signals for each recording medium, and It relates to storing information in a predetermined format on a storage medium such as an optical disk.

BACKGROUND OF THE INVENTION Information storage devices of this type are used to store image information, such as documents, which occur in large quantities, in a manner that is easy to retrieve. Various types of information storage devices of this type have been developed and put into practical use, especially recently. However, there are still many problems that need to be resolved, including ease of use.

The configuration of conventional information storage devices and their recitation points are briefly explained below. First, the order in which they were input, that is, at the beginning of the reading.

There is a method in which the captured image information, sound, and address information to distinguish it from other information are written onto a disk, which is a storage medium.

With this method, writing is performed in the order in which it is read, so if you want to store a large number of documents whose page numbers have been recorded in advance in the order of their page numbers, all of the documents must be manually arranged in the order of their page numbers. The inconvenience of having to do this arises.

Next, if it is a single type of document, there are some that are configured to file in order of page numbers without having to align all pages in advance. Ru. However, when the number of types of documents increases, the inconvenience arises that the documents must be manually organized by type in advance. Also, when reading a large number of documents, for example using an ADF (automatic document feeder),
Duplicate feeding of sentences with the same page number can easily lead to erroneous operations.

Purpose This invention was made in order to solve one or more erroneous problems.The purpose of this invention is to make it possible to arrange the information recorded in these documents on a single page even when handling a large number of various documents. Alternatively, the information can be stored on a storage medium such as an optical disk without the need for troublesome preliminary work such as organizing by type, and the storage state can be in a format suitable for later retrieval. , even large amounts of documents can be handled without placing a large burden on the operator.
An object of the present invention is to provide an information recording device that can be processed in an orderly manner.In order to achieve the above object, the present invention has a structure in which the image information recorded on each of a plurality of recording media is electronically stored on each recording medium. In an information storage device that sequentially reads out information in the form of a signal and stores the read information in a storage medium in a predetermined recording method, a code that specifies the type of s4i1 information before storing it in the storage medium. and the total number of pages of the recording medium in which information classified into the type specified by the code is recorded. A storage area corresponding to the total number of pages written is set in the storage medium for each type of code, and information read from the storage medium is stored in the storage area set for each code, sorted by type of each code. In addition, the recording medium that has been read and stored in the storage medium is discharged separately from other recording media.

Hereinafter, preferred embodiments of the present invention will be described based on the drawings. ◎ Fig. 1 shows the configuration of an information storage device according to an embodiment of the present invention.

In the device shown in the figure, the original disk 1 is used as an information storage device.
Use 3. The information recording medium is a document 1 using paper of a predetermined size and format. The main parts of the device are a reading section 6, a page buffer memory 7, an image information extraction section 8, a character recognition section 9, address memory 10,
The information recorded on the document 1 is read by the reading section 61C. The writing/reading is performed by the writing/reading section 12.

The document 1 as a recording medium is classified into 211t types depending on the type of information recorded therein. The first tumor document states:
Information regarding image information 2, information number 3, total page number 4, and page number 5 is recorded. Additionally, the second type of document includes:
Information other than total page number 4, i.e. image information 3, information number 3
, page number 5 contains the following information.

Here, the image information 2 is the main content of the document itself. Information number 3 corresponds to the code described above, and is identification information that specifies the first type of document. The total number of pages 4 means the total number of sheets of the document, that is, the total number of pages when the - type information is recorded across multiple sheets of the document. The page number 5 is a serial number assigned to each document, and is incremented by 1 from the lowest number (1) to the highest number.

The document 1 is automatically read by the reading unit 6 by the ADF, for example.
supplied to

The reading unit 6 includes a light source that illuminates the document 1, a photoelectric converter such as a COD (charge coupled device) that converts reflected light from the illuminated document 1 into an electrical signal, and an imaging optical system. has been done.

The page buffer memory 7 uses a so-called RAM (Random Access Memory) and has a storage capacity sufficient to store one unit (one page of a document) or several units (several pages of a document) of image information.

The image information extraction section 8 selects image information of a designated address area in the page buffer memory 7 from within the page buffer memory 7, and outputs it to the character recognition section 9.

The character recognition unit 9 recognizes the information number 3, the total page number 4, and the page number 5 using well-known character recognition means.

The address memory 10 contains address information on the optical disk 13.
remember.

The control section 11 centrally controls the operations of each section.

The writing/reading unit 12 includes a laser oscillator, an optical modulator that modulates a light beam from the laser oscillator according to written information during writing, an optical head that scans the rotationally driven optical disk 13 in the radial direction, and It is composed of these control units and the like.

Note that if a so-called semiconductor laser is used as the laser light generation source, there is no need for an optical modulator or the like, and the laser generation source can be integrated into the optical head.
The writing/reading section 12 can be significantly downsized.

The output unit 14 outputs the image information read from the optical disc 13, and there are two output formats to choose from: recording output as a so-called hard copy or display output using a CRT display or the like.

An operating keyboard 15 is used, for example, to issue commands to the device.

Next, the configuration of an information storage device according to an embodiment of the present invention is as follows.
This will be explained in more detail with reference to an example of its operation. First, as shown in FIG. 2, the format of the optical disc 13 is as follows: from the outer circumference to the inner circumference, the first writing area TI, the second writing area T2. Third writing area T3...
...The storage areas are divided and set in concentric circles.For example, the first writing area TIK contains the image information of the first page, and the second writing area T2 contains the image information of the first page. Each writing area Tl, the image information of the third page is written in the third writing area T3, and the image information of the third page is written in the third writing area T3.
T2. Each of T3... is made to correspond to one unit of image information.

Here, a case will be described in which a plurality of documents, which are not classified by information type and whose pages are in an irregular order, are stored in the order of information side and page number.

Among the plurality of documents, the first negative document has information number 3. The total number of pages is 4°, the page number is 52, and the image information 2 is recorded in advance. Moreover, at least information number 32 page number 59 image information 2 is recorded in advance in the documents after the second negative mark.

The above-mentioned document is supplied to the reading section 6 by the ADF. At this time, only the first member, that is, the first negative document in this case, is supplied first, and the other documents are supplied to the reading unit 6 with their information side classification and page order completely irregular. reactor.

Here, for ease of understanding, 5 is shown in Figure 3.
Next, a case will be explained taking as an example a case where a total of eight sentences 1 with two different information numbers 3 and each with a total number of pages of 5 and 3 are stored on the optical disk in the order of information side and page number.

The above 8 documents have incorrect information and page numbers.
in the previous state.

First, as shown in FIG. 4(a), the content of information number 3 is first supplied to the first negative document all reading section 6 of the document group rAJ. The reading unit 6 reads the entire document. The read image information is memorized and stored in the stamp buffer memory 7. The information stored in this +i buffer memory 7 includes information number 3, rich page number 4, page number 5, and image information for 1 unit 2.
It is included.

Next, among the information stored in the puffer memory 7, information number 3. Information regarding the total number of pages 42 page number 5 is output to the character recognition section 9, where information number 3゜total number of pages 42 page number 5
Each content of is recognized sequentially.

Thereafter, the controller section 11 determines address information on the optical disk 13 based on the information number 3 recognized by the character recognition section 9. This address information is obtained by converting the information number 3 using a predetermined addressing calculation formula. As a result, optical disk 1
3, a storage position at which to start storing the series of image information 2 corresponding to the information number 3, a so-called leading address, is designated.

Subsequently, the controller unit 11 secures an area for storing the entire document (all pages) of the same information issue based on the total page number 4 recognized by the character recognition unit 9.

In other words, if there is one page of a document with a certain information title, and the first address of this document is m, then m is from (, m +
The storage area up to n-1) is secured.

Further, the controller section 11 specifies the address position on the optical disk 13 where the read image information 2 is stored, based on the page number 5 recognized by the character recognition section 9 and the above-mentioned start address. If page number 5 is the first page, the writing area for the read image information is specified at the above-mentioned top address. Further, if it is after the second negative number, the writing area of the read image information is specified at an address after the above-mentioned top address by the number of page permissions.

The address information on the optical disk 13 determined as described above is registered and declared by being stored in the address memory 10.

In step 5 above, the writing area on the optical disk 13 is first secured for each information number 3 in a size corresponding to the total number of pages 4&C based on the recognition result of the character recognition unit 9, and Each start address is determined, and then individual addresses are designated for each page number 5.

For example, if the information number 3 recognized by the character recognition unit 9 is "A", the total number of pages 4 is "5", and the second page number 5 is "1", then the storage area for 5 pages is In order to ensure this, the first writing area T1 on the optical disk 13 is designated, as shown in FIG. 4(b).

At this time, assuming that the start address is set to address 0, five write areas from addresses 0 to 4 are reserved for information number rAJ.

Next, as shown in FIG. 5(a), information number 3 is "B".
When the first page of the document is supplied to the reading section 6, the reading section 6 receives the image information 2 and information numbers 3. Total number of pages 41 Page number 5t - Read and send to page buffer memory 7. After that, the image information extraction unit 8 extracts the above three identification information 3. 4. 5 are extracted, and the content of each is recognized by the character recognition unit 9. Then, based on the recognition result, the controller unit 11 repeats the same operation as in the above case.In other words, in this case, the recognized information number 3°, total number 41, page number 5 are rBJ and "3J", respectively.

Since it is "1", the first address is set to address 5,
Three write areas from here to address 7 are secured.

Then, the image information of the second and subsequent pages of information number rBJ read thereafter is stored at the address (6th address or 7th address J) corresponding to the page after the above-mentioned top address.

Note that the position of the writing area on the optical disk 13 is the fifth
As shown in Figure (b), the fifth recess area T5 and subsequent areas are allocated. Information number rBJ picture @! Information is written from the fifth writing area T5.

As described above, even if the document is not classified into the information side or the page order is irregular, after the first document is read, the information side classification and page alignment are automatically performed. and are recorded neatly on the optical disk 13 ↓5.

Next, the optical disc 1 on which the recording was performed as described above is performed.
The case where image information is read from 3 will be explained.

For example, if you want to read and output information by information number and page number order, input the information number and a command to that effect using the keyboard 15. As a result, the controller section 11 gives a command to the write/read section 12. The write/read unit 12 reads from the beginning of the write area on the optical disk 13 in which the image information with the information number is stored, and the read image information is transferred to the page buffer memory 7 via the controller unit 11. Ward is memorized. The page buffer memory 7 then outputs it as a hard copy or image display via the output unit 14.

Further, when extracting and outputting only a specific page number from a specific information number, the information number and page number are input from the keyboard 15, for example. In response to this, the controller unit 11 writes a control command to read the address information corresponding to the report number and page number from the address memory 1o and read the image information corresponding to the read address information. The readout unit 12 is provided with the readout unit 12 .

Here, in the above device, the first
It is assumed that a page is read and a margin is provided on the disk 13 for the total number of pages recorded in advance on the first negative side. Then, in the second reading, if the second and subsequent pages of the information number are read, the first negative document read in the first reading is used as the second and subsequent pages of the document. same as r9Tv
c- If the paper is ejected, there is a possibility that the first page will be read again in the second reading. The possibility of such a problem occurring must be considered extremely high in this type of information storage device that handles a large amount of documents.If a problem occurs in which this document is read multiple times, reading time will be wasted. Not only this, but in some cases, it may also cause reading errors.

Therefore, the above-mentioned apparatus is configured to eject documents that have been read and recorded onto the original disk, that is, filed documents, to a tray separate from unfiled documents. In other words, a document feed tray and a document discharge tray are provided separately. This prevents unfiled documents and filed documents from being stacked separately and being mixed together. Moreover, it is possible to handle a larger amount of documents in an orderly manner than with VC. Further, there is no need to separate unfiled documents and filed documents, thereby significantly reducing the operator's workload.

Note that in order to discharge filed documents and unfiled documents separately, it is only necessary to provide separate transport paths for each.

Effects As described above, even when handling a large number of documents of various types, the information storage device according to the present invention saves the troublesome preliminary work of arranging the information recorded in these documents such as aligning pages or organizing them by type. It can be stored on a storage medium such as an optical disk without having to perform a separate process, and the storage state can be in a format suitable for later retrieval.Furthermore, large amounts of documents can be stored without placing a heavy burden on the operator. It can be processed in an orderly manner without adding any extra effort.
